Our milk’s
life cycle assessment

Here’s how we measure our carbon footprint

What is an LCA?

A life cycle assessment or LCA, is a tool to measure the environmental impact of a product including its carbon footprint, from its production to its consumption to its disposal. This farm-to-fridge analysis goes across all phases of our milk’s lifecycle. It starts with what our cows eat and spans from our factories to milk delivery to the empty carton. It even includes spilled milk!

Our journey starts here

As we work towards a carbon positive future, we first need to quantify our milk’s carbon footprint. As a leader in organic dairy, we’re committed to transparency, so we’re sharing our LCA results.

Understanding our footprint with an LCA helps us pinpoint what phases in our milk’s lifecycle emit the most carbon dioxide and other greenhouse gases (GHG), so we can pinpoint ways to reduce emissions.

And the number is…

Our LCA found that a half-gallon carton of Horizon Organic whole milk has a carbon footprint of approximately 5.58 kg CO2e per half-gallon—that’s our starting point. The CO2e stands for “carbon dioxide equivalent” and includes other greenhouse gases like methane and nitrous oxide, which are more potent than carbon dioxide.

Life Cycle Assessment performed in accordance with ISO 14040 methodology using 2018 data for Horizon Organic whole milk half gallons produced in three Danone North America owned facilities.


With our LCA as a starting point, we’re rolling up our sleeves to help fight climate change. Together with our family farmer partners, we’re putting our hope for a brighter, more sustainable future into action. Learn more about our journey here.
